Description

Decafluoro-1,7-Heptanedioic Acid Dimethyl Ester is a highly fluorinated diester compound, valued for its unique combination of chemical inertness, thermal stability, and hydrophobic properties. This makes it a critical intermediate for synthesizing advanced materials and specialty chemicals where standard hydrocarbon-based molecules fail. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and high-performance polymer industries for developing novel fluorinated compounds.

Application

• Pharmaceutical Intermediate: Used in the synthesis of fluorinated active pharmaceutical ingredients (APIs) to enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key building block for creating advanced, weather-resistant herbicides and pesticides with improved efficacy.
• Fluoropolymer Modification: Acts as a monomer or cross-linking agent to introduce perfluoroalkyl segments, enhancing the chemical resistance and surface properties of polymers.
• Surface Treatment & Coatings: Imparts exceptional oil, water, and stain repellency to textiles, papers, and specialty coatings.
• Lithium-Ion Battery Electrolytes: Investigated as a fluorinated additive to improve electrolyte stability and battery performance under extreme conditions.
• Specialty Surfactants & Fluids: A precursor for manufacturing high-performance fluorosurfactants and heat-transfer fluids.

Quality Control

Our Decafluoro-1,7-Heptanedioic Acid Dimethyl Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from strong bases and sources of ignition. Due to its fluoride/strong alkali reactivity, ensure it is stored separately from incompatible materials.
